PPT-Eukaryotic Cells and Microorganisms

The Fungi The Fungi A Once thought to be plants but the cell wall is made of chitin rather than cellulose and these are not photosynthetic B Instead they are saprobic organisms that frequently live off of dead organic matter. A. Contaminants – microbes present at a given place and time that is undesirable. B. Decontamination – the removal or destruction of contaminants. C. Terminology. 1. Sterilization. A) Process that removes all viable microorganisms including viruses & endospores. Kingdom Protista. A. Sometimes not considered a true kingdom because the organisms vary tremendously from one to another. The only universal characteristic among the group is that they are all eukaryotic.. Mrs. McNutt.
